Scotland won 29-27 in Rome with the late drama rejecting the house side a very first 6 Countries win because 2015.
Tommaso Allan was almost the hero for the Italians, scoring 2 of their 3 shots, including all 3 conversions and scoring 2 charges.
All his efforts were in vain as the Scots came back from 12 points down in the 2nd half to take the video game late on.
Fraser Brown, John Barclay, Sean Maitland and Stuart Hogg crossed the line for the visitors.
Still, with 5 minutes staying Italy planninged to have actually protected success when Allan scored the second of his charges.
There was still time for one last twist and it came from the boot of Laidlaw after the Italians collapsed a whip.
That provided Scotland the lead, without any time for the house side to react and Gregor Townsend’s side for that reason end their Six Nations project with 3 success, beating France and Italy along with their Calcutta Cup win over England.
For Italy there was heartbreak and the wood spoon for the 3rd year in a row. When they beat Scotland 22-19 at Murrayfield, their last Six Nations triumph was back in 2015.
Scotland are next in action in June when they take a trip to play internationals in Canada, the USA and Argentina.
They are then back house for the fall worldwide series later on in the year, dealing with Wales in Cardiff prior to house video games versus Fiji and Argentina.
